Noninvertible symmetries from holography and branes by Apruzzi, F, Bah, I, Bonetti, F, Schafer-Nameki, S

“…We propose a systematic approach to deriving symmetry generators of quantum field theories in holography. Central to this analysis are the Gauss law constraints in the Hamiltonian quantization of symmetry topological field theories (SymTFTs), which are obtained from supergravity. …”

Conformal nets and local field theory by Douglas, C, Bartels, A, Henriques, A

“…Dualizable objects of this tricategory correspond to conformal-net-valued 3-dimensional local topological quantum field theories. We prove that the dualizable conformal nets are the finite sums of irreducible nets with finite µ-index. …”

Quasinormal modes of black holes and black branes by Berti, E, Cardoso, V, Starinets, A

“…Within the recently developed gauge-gravity duality, these modes serve as an important tool for determining the near-equilibrium properties of strongly coupled quantum field theories, in particular their transport coefficients, such as viscosity, conductivity and diffusion constants. …”

M$_k$ models: the field theory connection by T. Fokkema, K. Schoutens

“…This paper highlights connections with quantum field theories (QFTs) in various regimes. At criticality the QFTs are minimal models of ${\cal N}=2$ supersymmetric conformal field theory (CFT) - we analyse finite size spectra on open chains with a variety of supersymmetry preserving boundary conditions. …”

One-loop monodromy relations on single cuts by Ochirov, A, Tourkine, P, Vanhove, P

“…The discovery of colour-kinematic duality has led to significant progress in the computation of scattering amplitudes in quantum field theories. At tree level, the origin of the duality can be traced back to the monodromies of open-string amplitudes. …”

Unraveling the holomorphic twist: central charges by Bomans, P, Wu, J

“…The holomorphic twist provides a powerful framework to study minimally protected sectors in supersymmetric quantum field theories. We investigate the algebraic structure underlying the holomorphic twist of N = 1 superconformal field theories in four dimensions. …”

The landscape and the multiverse: what's the problem? by Read, J, Le Bihan, B

“…One current source of scepticism is that the theory can be used to derive, depending upon the input geometrical assumptions that one makes, a vast range of different quantum field theories, giving rise to the so-called landscape problem. …”

Sub-subleading soft graviton theorem in generic theories of quantum gravity by Alok Laddha, Ashoke Sen

“…Our results agree with known results in quantum field theories and string theory.…”

Renormalization for a Scalar Field in an External Scalar Potential by Stephen A. Fulling, Thomas E. Settlemyre, Kimball A. Milton

“…There is a residual dependence on the logarithm of the potential, reminiscent of the renormalization group in fully-interacting quantum field theories; these terms are finite, but numerically dependent on an arbitrary mass or length parameter, which is purely a matter of convention. …”

Renormalised spectral flows by Jens Braun, Yong-rui Chen, Wei-jie Fu, Andreas Geißel, Jan Horak, Chuang Huang, Friederike Ihssen, Jan M. Pawlowski, Manuel Reichert, Fabian Rennecke, Yang-yang Tan, Sebastian Töpfel, Jonas Wessely, Nicolas Wink

“…We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditions, hence implementing a flowing renormalisation. …”

Scattering in the Ising model with the quantum Lanczos algorithm by Kübra Yeter-Aydeniz, George Siopsis, Raphael C Pooser

“…Time evolution and scattering simulation in phenomenological models are of great interest for testing and validating the potential for near-term quantum computers to simulate quantum field theories. Here, we simulate one-particle propagation and two-particle scattering in the one-dimensional transverse Ising model for 3 and 4 spatial sites with periodic boundary conditions on a quantum computer. …”

Baikov representations, intersection theory, and canonical Feynman integrals by Jiaqi Chen, Xuhang Jiang, Chichuan Ma, Xiaofeng Xu, Li Lin Yang

“…Abstract The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases are closely related to d-dimensional d log-form integrands. …”

New Developments in Relativistic Magnetohydrodynamics by Koichi Hattori, Masaru Hongo, Xu-Guang Huang

“…We discuss how the transport coefficients in RMHD are computed in kinetic theory and perturbative quantum field theories. We also explore the collective modes and instabilities in RMHD with a special emphasis on the role of chirality in a parity-odd plasma. …”

Non relativistic limit of integrable QFT and Lieb–Liniger models by Bastianello, A, De Luca, A, Mussardo, G

“…This limit amounts to sending to infinity the speed of light c but simultaneously adjusting the coupling constant g of the quantum field theories in such a way to keep finite the energies of the various excitations. …”

Emergent symmetries and coexisting orders in Dirac fermion systems by Emilio Torres, Lukas Weber, Lukas Janssen, Stefan Wessel, Michael M. Scherer

“…We consider interacting (2+1)-dimensional Dirac fermions with competing symmetry-breaking electronic instabilities, as described by relativistic quantum field theories of the Gross-Neveu-Yukawa flavor with anticommuting mass terms. …”

Constructing CFTs from AdS flows by Markus B. Fröb

“…Abstract We study the renormalization group flow equations for correlation functions of weakly coupled quantum field theories in AdS. Taking the limit where the external points approach the conformal boundary, we obtain a flow of conformally invariant correlation functions. …”

Topological entanglement entropy of fracton stabilizer codes by Ma, H, Schmitz, A, Parameswaran, S, Hermele, M, Nandkishore, R

“…Entanglement entropy provides a powerful characterization of two-dimensional gapped topolog- ical phases of quantum matter, intimately tied to their description by topological quantum field theories (TQFTs). Fracton topological orders are three-dimensional gapped topologically ordered states of matter that lack a TQFT description. …”
